You can create machine prefixes that are used to create names for machines provisioned through vRealize Automation. A machine prefix is required when defining a machine component in the blueprint design canvas.
About this task
A prefix is a base name to be followed by a counter of a specified number of digits. When the digits are all used, vRealize Automation rolls back to the first number.
Machine prefixes must conform to the following limitations:
Contain only the case-insensitive ASCII letters a through z, the digits 0 through 9, and the hyphen (-).
Not begin with a hyphen.
No other symbols, punctuation characters, or blank spaces can be used.
No longer than 15 characters, including the digits, to conform to the Windows limit of 15 characters in host names.
Longer host names are truncated when a machine is provisioned, and updated the next time data collection is run. However, for WIM provisioning names are not truncated and provisioning fails when the specified name is longer than 15 characters.
vRealize Automation does not support multiple virtual machines of the same name in a single instance. If you choose a naming convention that causes an overlap in machine names, vRealize Automation does not provision a machine with the redundant name. If possible, vRealize Automation skips the name that is already in use and generates a new machine name using the specified machine prefix. If a unique name cannot be generated, provisioning fails.
